Abstract:

During the donation process, the source and flow of donated goods are not disclosed to the public in time. In this paper, we propose the donation tracing blockchain model (DTBM) to render the donation process open and transparent, by using blockchain with decentralization, traceability, and anti-tampering. However, the existing blockchain systems have a problem that the process of Delegated Proof of Stake (DPoS) consensus algorithm is easily controlled by a few nodes. To prevent the centralization and reduce the probability of malicious nodes being selected, we propose an improved DPoS consensus algorithm for DTBM. It adopts the K-means algorithm to select good nodes in the agent queue in advance. Experimental results show that the donation process is transparent and traceable in DTBM. And it also solves the problem of centralization and improves security.
